WATER-HEATER.

Application filed March 9, 1911. Serial No. 613,345.

T 0 all whom it may concern:

Be it known that I, BENJAMIN E. MEA- CHAM, a citizen of the United States, residing at Lorain, in the county of Lorain and State of Ohio, have invented certain new and useful Improvements in Water-Heaters, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in water heaters.

The object of my invention is to provide a heater in which the inner andouter shells are so connected together that they can be readily separated, so that the scale deposit from the water can be readily removed from the walls of the inner and outer shells orcasings.

Another object of my invention is to provide a more simple, cheap and elfective heater of this character having certain details of structure hereinafter set forth.

In the accompanying drawings- 1 Figure 1 is a vertical sectional view of a water heater embodying my invention. Fig. 2 is a transverse horizontal sectional view Fig. 3 is a perspective view of the clamping ring.

Referring now to the drawing, 1 represents the outer casing of my improved heater in which is removably located the inner shell or casing 2 spaced some distance from the outer casing to form a space to hold the proper body of water. The inner casing 2, as shown, is corrugated" horizontally or transverse thereof to form a larger heating surface and thus increasing the heating capacity of the heater without increasing the size thereof, resulting in the saving of fuel.

The inner shell or casing 2, as is well understood, forms the central smoke flue and has its upper end drawn inwardly as indicated at 3, and provided with the contracted smoke discharge pipe 4, which is in communication with a chimney or the outside atmosphere in any desired manner. The inwardlydrawn portion 3, of the inner shell, is provided with the llat horizontal seat 5,

upon which a suitable packing 6 is placed,

and the upper end of the-outer shell or casing 1 is drawn inwardly at 7 ,{and rests upon said packing whereby a tight joint is formed to prevent the leakage of Water from between the outer and inner shell or casing.

The lower end of the inner Shell is made without the corrugations, as indicated at 8, which gradually flares outwardly to bring the lower end closer to the outer shell. The extreme lower end of the smooth portion 8 of the inner s'hell2 is formed with a circumferential laterally extending flange 9, formed with a smooth upper face 10, forming a support for the-packing 11. The lower end of the outer casing is provided with an in wardly' extending flange 12, which rests :upon the packing 11; The casing 1 is also provided with an outwardly and downwardly extending flange 13. The vertical inner wall 14 ofsaid fiange bears tightly against the outer edge of the flange 9 of the inner shell or casing.

The flange 13 forms a horizontal flat face tending lugs 17 on its upper face, and upon which the flange 9 is supported, the base or ring being supported by feet or in any other desired manner. The lugs 17, as will be seen, space the flange 9 from the base 16, and

thus form air passages between the same for feeding an to the burner.

Specification of Letters Patent. 'Pgttented J 1111 30, 1914 i The ring or base 16 is, as shown, provided With the central opening 13, in which is located the burner 19, supplied with fuel.

through the pipe 20. The burner. as shown,

is of a diameter less than that of the opening and thus an annular air passage 21 for supplying additional air to the blirner is provided.

The outer casing at its'lower end is provided with a water supply pipe 22, which supplies the space 23, between the outer and inner casing ,with water, and the upper end is provided with a discharge pipe 2 1.

The outer edge of the base 16 is provided with the outwardly extending cars 25, hava ing openings. Resting upon the upper flat face 1 1 of the flange 13, is the clamping ring 15, provided with the outwardly extending lugs 27 having slots 28. The said ring is provided with an upwardly bowed portion 29, which is adapted to pass upwardly over the pipe connection 30 with the casing.

Bolts 31 pass upwardly thrpugh the openings 26 in the base 16, and thrpugh the slots 28 in the lugs 27, whereby the ring is drawn tightly down upon the flange 13 and clamps the lower end of the outer casing upon the flange 9 of the inner casing and shell and by means of the packing 11 a tight joint is formed. The tightening of the bolts 31 also draws the inwardly extending end 7 of the outer casing or shell '1 down upon the packing carried by the inwardly drawn portion 3, of the inner casing or shell 2, and thus" a tight connection is made at the upper end by means of the packing.

From the foregoing description it will be understood that by loosening the bolts 31 of nuts carried thereby moving the same out of the slots 28 in the lugs 27, the inner shell or casing 2 can be removed so that any deposit from the water can be readily removed from the casing. The removal of the inner sections allows the heater to be cleaned without disturbing the water connect-ions with the tank.

The flue l of the inner casing is provided with a cross-bar 32 to which is secured a downwardly extending bolt or rod 33, and

said bolt has the baffle plates 34 secured thereon. The said baffle plates, as shown, are

arranged opposite the outwardly extending corrugations, so that as the heat or products of combustion" strike the battle plates the same is caused to travel outwardly into the corrugations and thus increase the passage from the burner to the flue l, and materially increasing the heating capacity of the heater. The lower end of said bolt or rodis provided with the inverted bell-shaped baflie 35, the lower end of which is just above the portion 8 without the corrugations.

Having thus described my invention, what I claim and desire to secure by Letters Patent is f l. A water heater comprising an inner casing, an outer casing resting upon the inner casing at its upper and lower ends and spaced therefrom, a base having upwardly extending lugs on its inner face and upon which the inner casing rests, a clamping ring engaging the outer casing and bolts passing through the base and the clamping .ring and clamping the two easings together at their upper and lower ends.
